    Heats of Hydration and Absolute Heats of Formation of Aqueous Ions
    (1968-03) Myers, R. Thomas
    Accurate calculations are made for the hydration energies of the alkali halides, using the most recent data. These results, and the average of theoretical calculations made by others for the individual ions, are used to determine the most probable hydration energy of the individual ions. These in turn are the basis for calculating the absolute enthalpy of formation of aqueous H+: 98.6 kcal/g-equiv. A Born-Haber cycle can then be used to calculate the hydration energy of any other ion for which the enthalpy of the gaseous ion is known.

    The Effect of Malchite Green as a Fungicide
    (1968-03) Martin, Richard
    A series of tests with malachite green, used at various concentrations and treatment durations, were made on six species of watermolds known to be parasitic on fish and/or fish eggs. The tests indicate that these species have markedly different tolerances to the dye. While a treatment of as little as 1 ppm of malachite green for five minutes was effective for Saprolegnia parasitica, it took 10 ppm for five minutes to control Achlya ambisexualis and Allomyces macrogynus, and 15 ppm for one hour to control Achlya oblongata.

    The Occurrence and Origin of Small Mammals on the Islands and Peninsulas of Western Lake Erie
    (1968-03) Fall, Michael W.; Jackson, William B.; Carpenter, Michael L.
    Collection of small mammals in the island and peninsula region of western Lake Erie from 1962 to 1967 has provided information on the present distribution of several species. The white-footed mouse (Peromyscus leucopus noveboracensis) was found in wooded areas throughout the region except on two of the smallest islands. Other native small mammals were trapped on Catawba and Marblehead Peninsulas but were not found on any of the islands. Various classical methods by which mice reach islands were considered in reference to the Lake Erie situation. None seemed appropriate for direct movements from mainland to island. Swimming, rafting, and movement across ice may be effective for the shorter inter-island and mainland-to-peninsula movements, but no adequate natural explanation for the longer movements can be offered. Human activity may aid in maintaining mouse populations on the smaller islands, but the limited diversity of island smallmammal fauna suggests a minor role for man in the importation of new animals.

    Amino Acids and Peptides. XIV, Synthesis of a Tetrapeptide Sequence (A5-A8) of Glucagon
    (1968-03) Handford, Brian O.; Hylton, Thomas A.; Weinstein, Boris
    A synthesis of the tetrapeptide sequence A5-A8 of glucagon is described that employs various blocking groups, coupling procedures, and routes.

    Wet Analysis of Gold-Silver Alloys of High Gold Content
    (1968-03) Caley, Earle R.; Shank, Lowell W.
    Gold-silver alloys dissolve completely in mixtures of hydrochloric and nitric acids acids containing potassium chloride in high concentration. In an analytical procedure based on this observation, silver is separated and determined as the chloride, and gold as the metal after reduction with sulfite. Analyses of test alloys, synthetic mixtures, and ancient objects showed that this new procedure is practicable and that results of satisfactory accuracy can be obtained.

    Distribution and Implications of Sponge Spicules in Surficial Deposits in Ohio
    (1968-03) Wilding, L. P.; Drees, L. R.
    Microscopic examination of biogenic opal isolated from the 0.05-0.02-mm total mineral fraction of 12 upland soil profiles indicates that fragments of sponge spicules are minor but ubiquitous constituents of Ohio soils, with major concentrations in the upper 10 to 15 inches of the profile. Quantities range from about 30 to 2000 parts per million biogenic opal or 1 to 65 parts per 10 million parts soil. Spicules are absent or extremely rare in calcareous Wisconsin-age till deposits. Their correlation with horizons high in silt content (50-75%), and their size and depth distribution in landscape positions which preclude an authigenic origin, indicate their aeolian transport from aquatic source areas with other loessial materials. Identification of spicules thus provides direct evidence that these horizons have been derived from loess or loess-till admixtures. This microscopic technique may serve useful for the identification of loess when field or laboratory particle-size analysis yields inconclusive evidence.

    Histochemical Studies on Two Milliped Species
    (1968-03) Bowen, Raymond C.
    Histological and histochemical tests give similar results for the midguts of Floridobolus penneri (Causey, 1957) and Narceus gordanus (Chamberlin, 1943). The peritrophic membrane is composed of basic proteins and acid mucopolysaccharides. The epithelium contains basic proteins and large lipid concentrations, including glycolipids, phospholipids, and fatty acids. The luminal epithelial border gives reactions for protein-bound amino groups, tyrosine and phenolic compounds, and neutral fats. Protein-bound amino groups, glycoproteins, acid mucopolysaccharides, and bound lipids are found in the collagenous basement membrane. The circular and longitudinal muscle layers contain basic proteins, tyrosine and phenols, and bound fats. A large glycogen concentration occurs within the sheath membrane. This region, which is primarily basic protein, also gives positive reactions for protein-bound groups and both tyrosine and phenols.

    Algae from Western Lake Erie
    (1968-03) Taft, Clarence E.; Kishler, W. Jack
    Four species of algae in the Chlorophyta and five in the Cyanophyta are newly reported for Western Lake Erie. Gongrosira stagnalis (G. S. West) Schmidle, collected from the basal fragments of old Cladophora, appears to be a new record for the United States. Nephrocytium obesum W. & G. S. West, which is reported as often having a shallowly scrobiculate wall, is unique and merits further intensive study.

    Landslides of Southeastern Ohio
    (1968-03) Fisher, Stanley P.; Fanaff, Allan S.; Picking, Larry W.
    The Upper Pennsylvanian and Permian cyclothemic sedimentary rocks of the Ohio River valley are especially subject to downslope movements. Repairs of landslides on state highways in eastern Ohio alone cost over a million dollars annually. Eighty-seven slope failures were located within seven counties of southeastern Ohio; 50 of the larger of these movements were mapped in some detail. Earthflows and rotational slumps are the most common types of slope failures, the latter being the larger and constituting about 89 percent of the landslides mapped. Over 70 percent of the total number of slope movements occur within only one-sixth of the geologic column. Red shales predominate in the four most unstable intervals; the gray shales of the area seldom yield to sliding and the green shales vary greatly in strengths. Almost all of the red shales and one-third of the green shales slake completely within three hours after immersion in water; many of the red shales deteriorate to an ooze within minutes. There is no apparent relationship between stability and the amounts of soluble salts in each type of shale. Differential thermal analyses and rehydration tests indicate that these shales are composed largely of illitic clay minerals which, in the red shales at least, are deficient in bonding by cations of potassium. Ferric ions, presumably connate, have prevented readsorption of potassium throughout time, thus permitting a thickening of the interlayer water with resultant weakening of bonding. When interlayer water is driven off, a faster and greater regain is noted in the more unstable shales, as compared with that in the relatively stable shales. When the unstable shales are replenished with potassium, they strengthen markedly, especially those samples from which much of the inhibiting iron oxides have previously been removed.
